Description

[Detailed Description of the Invention] ``Technical Field of the Invention'' The present invention relates to an improvement in the structure of a waterproof grommet fitted between the conduits of two control cables (hereinafter simply referred to as cables). More specifically, the present invention relates to a structure that ensures waterproofing of each cable by symmetrically engaging grommets fitted to two cables to form a pair.

``Prior Art'' Conventionally, as a structure for waterproofly fixing two cables to the body of a vehicle using one waterproof grommet, there was a structure as shown in Fig. 3, for example. . That is, the base 12 of the grommet 11 is provided with two conduit holding parts 13, 13', and either one of the holding parts (in FIG.
3'), a slit 14 is provided along the entire length including the base 12 of the grommet. When assembling a cable using such a grommet, assemble one cable by inserting the conduit into the non-slit side of one holding part (13 in Figure 3), and then inserting and fitting the grommet. Separately complete the assembly of the other cable that is not attached, and insert this cable into the slit 1 provided in the holding part 13' of the grommet fitted to the one cable.
4, the conduit is fitted into the holding portion, so that two cables are assembled into one grommet.

If the grommet does not have a slit as described above, two conduits must be inserted into one grommet. Since assembly is extremely difficult, a slit is provided and a cable is later fitted through the slit. However, in the case of grommets with slits as described above, if rainwater etc. comes into contact with the grommet after the cable is attached to the car body, the slits will absorb the water through capillary action and the water will enter the car interior and enter the car body. It causes rust. For this reason, a waterproofing treatment using caulking material is applied around the slit portion, but this cannot be a complete waterproofing treatment and at the same time, extra steps such as applying caulking material must be performed.

``Purpose of the invention'' The purpose of the invention is to eliminate the drawbacks of the conventional waterproof grommet for cables, and to provide a waterproof grommet with a structure that can hold two cables and reliably obtain a waterproof effect. .

``Structure of the invention'' In order to achieve the above-mentioned purpose, two grommets are integrated by engaging and fitting symmetrically to ensure a waterproof effect, and the base of the grommet and the It consists of an engagement hole drilled at an appropriate position in the base, an engagement protrusion bored at a position symmetrical to the engagement hole, and a conduit holding part provided in the engagement protrusion.

``Embodiments'' Next, the waterproof grommet of the present invention will be described with reference to the drawings, but the present invention is not limited to such embodiments.

FIG. 1 is a front view of an embodiment of the waterproof grommet of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A in FIG.

In FIG. 1, a grommet 1 has a base 2, and an engagement hole 4 is bored on one side of the base with a line of symmetry in the vertical direction in the drawing as a boundary, and the other side is engaged with the engagement hole 4 at a symmetrical position. A protrusion 5 is provided in a protruding manner, and the engagement protrusion has a holding portion 3 for holding a cable conduit.
is provided.

"Effect of the invention" Since the waterproof grommet 1 of the present invention has only one cable holding part 3, the waterproof grommet of the present invention is fitted to each cable in a set during the cable manufacturing process. After that, the engaging hole 4 and the engaging protrusion 5 provided on each waterproof grommet fitted to the two cables are connected to the engaging protrusion 5 provided on the other grommet. 4, respectively, as shown in the cross-sectional view of FIG.
The individual grommets can be assembled into a vehicle body or the like. In this case, the waterproof effect is equivalent to that of fitting one grommet to two cables, and at the same time, there is no slit in either of the holding parts, and there is no need for one. There has never been a waterproof grommet with such a structure before, and this different structure allows the device to exhibit extremely excellent waterproofing effects that have never been seen before.
